• fix regression causing frozen components
• fix dependencies for anonymous users, move window.resize event to setUp function to prevent anon users from receiving it
• update readme
• change jquery selector context to find calls
• Code cleanup

Bugs:
- A critical bug has been fixed that prevented accounts from being deleted because account cleanup called methods to delete or change ownership on all of the to-be-deleted account's content. And those methods crashed.

Internal notes:
- Based on internal version Version 0.6.7

Adds

- #79: Adds proxy for querying Solr backend, making this module work with Acquia Search and significantly hardening security.
- #83: Adds ability to set default query field in settings.php as opposed to relying on custom Solr Config (for queries that use the proxy provided by this module)

This is a beta release for the next feature release of Drupal 8. Betas are good testing targets for developers and site builders who are comfortable reporting (and where possible, fixing) their own bugs. Beta releases are not recommended for non-technical users, nor for production websites. More information on beta releases.
